A three-dimensional solver for simulating reactive flow on curvilinear parallel adaptive meshes
A generic solver in a parallel Cartesian adaptive mesh refinement framework is extended to simulate reactive flows on structured curvilinear meshes. A second-order accurate finite volume method is used with a grid-aligned Riemann solver for inviscid thermally perfect gas mixtures. Detailed, multi-step chemical kinetic mechanisms are employed with a splitting approach. The prolongation and restriction operators are modified to implement the adaptive mesh refinement algorithm on a mapped mesh. The developed solver is verified with a multispecies shock tube problem and is then used to simulate rotating detonation waves in an annular combustion chamber. The results show that the new solver can simulate high-speed reactive flows efficiently.

Abstract
A generic solver in a parallel Cartesian adaptive mesh refinement framework is extended to simulate reactive flows on structured curvilinear meshes. A second-order accurate finite volume method is used with a grid-aligned Riemann solver for inviscid thermally perfect gas mixtures. Detailed, multi-step chemical kinetic mechanisms are employed with a splitting approach. The prolongation and restriction operators are modified to implement the adaptive mesh refinement algorithm on a mapped mesh. The developed solver is verified with a multispecies shock tube problem and is then used to simulate rotating detonation waves in an annular combustion chamber. The results show that the new solver can simulate high-speed reactive flows efficiently.
